Hi! I'm trying the learn about the blood vessels of the brain. I'm looking for help to understand this all. I understand that there's the carotid artery supplying the brain and then you have the circle of wills and both the middle anterior and posterior arteries but.
What is the diameter of these vessels?
How can I learn about the dynamics of bood flow? At what regions in the major cerebral arteries does most blood leave?...
Is everything "connected" to each other? For example if there was a block would blood come from another artery to compensate this?
How large are the capilaries in the white and grey matter? How many are there say running through a 5x5 mm region? Are they as small as blood vessels?
What happens if there is a leak in the brain-blood barrier? -Does the whole interstitual space become filled?
Please help me understand the anatomy and dynamics of blood flowing through the brain. Where/ how can I best learn this?
Thanks!

correction:
"are they as small as blood vessels" should be "are they as small as red blood cells"

You are asking for a reply on a subject that takes years to learn about!
Rather than get into it all here..... which would take pages and pages, ~ type the words "vascular system of the brain" into your search engine.
This will give you dozens ~ hundreds even ~ of sites which will explain EVERYTHING you want to know, very clearly and concisely.
You will be able to choose from scholarly articles on the subject, or ones more geared to the lay person. Good luck!

the circle of willis does indeed allow one carotid artery to provide circulation to both sides of the brain should the other carotid artery become occluded. this has been known to happen with severe carotid stenosis.
